Gaetano Rocco
Intraoperative assessment of surgical margins when lung nodules are to be removed can be a challenging undertaking. With the increasing use of sublobar resections, the need to define, either thoracoscopically or in open surgery, the safe margins for the intended wedge or segmentectomy are presumed based on the individual surgeon's expertise and experience. A new instrument is introduced to measure safe margins according to the current evidence from the literature by tattooing the lung around the nodule at a distance based on the maximum diameter of the nodule assessed at computed tomography...

We report a case in which abdominal tattoo margins were modified and used to hide the surgical incision for desmoid tumour removal. Our patient is a 37-year-old female with history remarkable for atrial septal defect closure at the age of ten, but not for previous abdominal surgeries or trauma. A desmoid tumour diagnosis was made upon needle biopsy of the 5 × 4 cm2 mass confined to the rectus abdominis. Subsequently, tumour was resected with an incision through the tattoo upper margin and abdominal wall was reconstructed with primary fascial closure mesh reinforced...

Here we describe a new mouse model that exploits the pattern of expression of the high-affinity IgG receptor (CD64) and allows diphtheria toxin (DT)-mediated ablation of tissue-resident macrophages and monocyte-derived cells. We found that the myeloid cells of the ear skin dermis are dominated by DT-sensitive, melanin-laden cells that have been missed in previous studies and correspond to macrophages that have ingested melanosomes from neighboring melanocytes. Those cells have been referred to as melanophages in humans...

The pathogenesis, diagnosis and therapy of sarcoidosis as an autonomous disease are subjects of spirited discussions, which haven't found definitive conclusion yet. Distinguishing between sarcoidosis and sarcoid-like reactions (sarcoid - type granulomas) is not currently a medical "gold standard" and is not implemented in clinical practice. This leads to 1) misinterpretation of numerous available data; 2) difficulty in the interpretation of other unverified data, which is often followed by 3) inappropriate or inadequate therapeutic approach...

Background and aims: The selective removal of tattoos and benign cutaneous pigmented lesions with laser energy evolved rapidly with the development of the nanosecond-domain Q-switched laser (ns-laser). Recently, however, a series of picosecond-domain lasers (ps-lasers) with pulsewidths less than 1 ns has become commercially available, enabling more efficient and faster removal of pigmented lesions in the field of dermatologic laser surgery. Rationale behind the ps-laser: The efficacy of the ns-laser depended on the theory of selective photothermolysis, whereby an extremely short pulse width was delivered less than the thermal relaxation time (TRT) of a target...

REVIEW
Yeliz Emine Ersoy, Huseyin Kadioglu
Breast cancer patients who present with nodal metastasis receive neoadjuvant chemotherapy (NAC) with increasing frequency and can have complete pathologic response after treatment. In this clinical scenario, sentinel node mapping and biopsy are gaining acceptance instead of axillary dissection to avoid morbidity. Biopsy proven positive lymph nodes must be reliably excised and examined after NAC to further decrease the false negativity rate of sentinel lymph node (SLN) surgery. The standard method for axillary staging in breast cancer patients even after NAC is SLN biopsy (SLNB) with a radioisotope, blue dye, or both (dual technique)...

The novel picosecond lasers, initially developed for faster tattoo removal, have also shown great efficacy in endogenous pigmentary disorders. To describe the efficacy and safety profile of an alexandrite (755-nm) picosecond laser in a wide range of pigmented flat and elevated cutaneous lesions. A retrospective study was performed in which we collected all the clinical images of patients treated with the 755-nm alexandrite picosecond laser for 12 months (November 2016-November 2017). Clinical features were obtained from their medical charts...

The primary objective of medical tattooing is to restore part of a patient's physical integrity. Moreover, the procedure seeks to assist in psychological recovery from the physical and/or psychological consequences of disease, surgery or trauma. The method described in this brief note marks a step forward in the field of such tattooing. The treatment simulates reconstruction of the nail bed, as the nails of the big toes had previously been removed through a surgical avulsion procedure. This treatment, agreed with the physician and performed by a tattooist with proven experience in medical tattooing, also involved the use of specific colour nuances that resulted in an extremely realistic outcome...

BACKGROUND AND AIMS: As a result of previous manipulation or submucosal invasion, GI lesions referred for EMR frequently have flat areas of visible tissue that cannot be snared. Current methods for treating residual tissue may lead to incomplete eradication or not allow complete tissue sampling for histologic evaluation. Our aim is to describe dissection-enabled scaffold-assisted resection (DeSCAR), a new technique combining circumferential ESD with EMR for removal of superficial non-lifting or residual "islands" with suspected submucosal involvement/fibrosis...

OBJECTIVE: Permanent hypopigmentation of burn scars is a common consequence after partial and full thickness burns that heal by secondary intent, and they can cause severe aesthetic issues. The surgical goals for effective treatment of postburn hypopigmentation are to remove scar tissues, and to produce healthy melanocytes, with minimal donor site morbidity. This article reviews the current literature about the different ways to treat hypopigmentation following burn injuries and discusses the indications...

BACKGROUND AND AIM: Preoperative endoscopic tattooing is an effective procedure to identify small intraoperative neoplasms. However, there are no defined criteria with regard to the indications for endoscopic tattooing of these lesions at the time of diagnosis. The aim of this study was to establish endoscopic criteria that allow the selection of patients who will need a tattoo during the diagnostic colonoscopy. METHODS: An ambispective study of patients undergoing laparoscopy due to a colorectal neoplasia who underwent endoscopic tattooing during the period from 2007-2013 and 2016-2017...

BACKGROUND: Recent studies show that near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) has the potential to improve the performance of sentinel lymph node (SLN) mapping. The current cohort study was designed to assess the value of the combination of ICG and methylene blue (MB) dye in patients undergoing SLN biopsy. METHODS: A prospective self-controlled trial was designed to detect the difference in the detection efficacies of ICG, MB, and combined ICG and MB (ICG + MB) navigation methods...

BACKGROUND AND OBJECTIVE: Ablative fractional laser treatment uses thousands of very small laser beam wounds to damage a fraction of the skin, which stimulates tissue remodeling. Each open micro-wound heals without scarring, but the amount of skin tightening achieved is limited. This animal study was performed to test the hypothesis that immediate temporary closure of fractional laser wounds could increase skin tightening after fractional ablative laser treatment. MATERIALS AND METHODS: Four adult swine were used for the study; 98 square test sites (3 × 3 cm) were tattooed on the abdomen and flanks of each pig...

Tattoos are common in the United States; however, tattooed persons may be perceived as having more negative character and as more deviant than people without tattoos. College students (Study 1) and community members (Study 2) viewed images of men and women with tattoos or the same images with the tattoos digitally removed and rated the targets' characteristics. Half of the participants viewed a target with a tattoo, and half viewed that target without it, allowing for both within- (participants all rated one male and one female target with a tattoo and another without) and between-participants (participants rated either the tattooed or non-tattooed version of a single target) comparisons...
